Standard Method of Test for
Developing Early-Age Compression Test Values and
Projecting Later-Age Strengths
AASHTO Designation:T 276-97 (2005)
ASTM Designation:C 918-93
SCOPE
1.1.This test method covers a procedure for making, curing, and testing specimens of concrete stored under conditions intended to measure the maturity
as it relates to strength gain in the concrete.
1.2.This test method also covers a procedure for using the results of early-age compressive-strength values to project potential strength of concrete at later ages.
1.3.The values stated in inch-pound units are to be regarded as the standard.
1.4.This standard may involve hazardous materials, operations, and equipment.
This standard does not purport to address all of the safety concerns associated with its use.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
